ROTARY PUMP.

1,030,166. Specification of Letters Patent.

Application Vfiled VSeptember 12., 1911. Serial No. 648,845.

Bc itknown that I, RALPH H. DANNER, a itizen ofthe United States, and a resident of Los Angeles, in thecounty of Los. Angeles and State of California, have invented va new and Improved Rotary' Pump, of which the :following is a full, clear, and exact description. v

The object ofthe invention is to provide a new and improved rotary pump, more especially designed for use in bored or driven wells, and arranged to prevent the bearings O f the pump shaft from being cut-by sand or other extraneous matter.

' For the purpose mentioned, use is 'made of a fixed bearing postextending -centrally in the well casing, pumping elements having hubs journaled on the said post, and a tubular driving shaft connected withthe hubs .of the pumping elements and through which extends ,looselylthe xed bearing post.

A practical embodiment of the invention is .represented in the accompanying drawingsforming a part of this specification, in

which similar characters of reference indicate corresponding parts in all the views.

Figure l'is a sectional side elevation of :the rotary pump with'the parts' shown in' elevation; Fig.' 2 l.is an enlarged-sectional `'side elevation ofthe upper portion of the "rotary pump; Fig. 3 is a like view of the lower portion of the pump; and Fig. 4 is' a sectional plan view of the same on the line 44-4 of Fig. 3.

.The Well casing A is preferably made` in tubular sections A, A2,A3 and A4, ofwhich the adjacent ends of the-sections A and A2 I 'are connected with each other by screwing into a collarB, and the adjacent ends of the sections A2 and A3-serew into a similar col-,4,` lar B-, while the section A'2 is-bolted or otherlwise fastenedto the top 4ofthe uppermost section As and the top section A4 is pro- 'vided with an outlet A5 fori the discharge form an inlet for the water.

On the upper end of the top section A4 is secured a bracket C, and a bracket D is secured on the lower end of the lowerrnost section A of the well 'casing A to The bracket D ispreferably provided with a central portion' D lfrom which radiate arms D2 connected with a ring D3 provided with an exlteriorfscrew thread screwing into a collar E screwing on the lower end of the lowermost casin section AQ .l y Within t' e casing A-sarranged a series I of pumping elements F, F and F2, preferably formedof propellers, and having their hubs F 3 ymounted to turn on a bearing post G, ixle'rl'at its ends in the top and bottom brackets C and D, and the said hubs F3 are connected with tubular sections H, H and H2 forming the driving shaft for the pumption of the upper sectionH2 being provided with a' pulley I connected by'a belt I with tion to the driving vshaft and the pumping driving shaft. y n

through which extends the lxed bearing elements F, F and F2 can be readily filled extraneous matter Icannot pass to the bearpumping elements andl the bearing post G, and consequently the said bearings are not liable 'to be cut up by the sand, grit or other extraneous matter,'and long life of the rotary pump' isjnsu'red. It is further under# stood', that the pumping elements are spaced suit-able distancesapart, and as many-pumpingelements are employedy as required ac ,cording 'to' the depth of the'well, each pumping element pumping th'e water upwardin spiral form inthe casing A to the next guiding element N, at which the next pumping element takes hold of thel water and forces it upward in the casing A, the same as the first pumping element, and this operation -is repeated until the water finally reaches' the outlet spout A5 in the top section Aiof the 'well'casing `By reference to the drawings, it will be' Patent: a

1Q A rotary pump'of the Class described, provided with a central bearing post, a seriesv of pumping elements having tubular portions circumjacent said post, tubular members also circumjacent said post and connecting said pumpingelements in spaced relation, said'tubular members and said tubular portions of'said pumping elements being spaced from the-said postk and forming a tubular driving shaft, means for driving said shaft, and meansfor closing the lower end of said driving shaft to prevent the entrance -of any of the fluid beingv pumped.

i 2f Arotary pump of the class desc `bed, comprising a well casing, a bearing pos ieljr tending centrally in t-he said well casing and?"j fixed at its ends a series of um in elements mounted circuinjacent the saidbearing post within the said well casing, tubular.-

members also circumjacent.` the post and connect-ing the pumping elements and forming therewith a tubular driving shaft, the.

said, bearing post -extending loosely through the said driving .shaft sections and means to close the lower end of saiddriving shaft to prevent the entrance of any of the fluid being pumped.

3. A rotary pump ofthe class described provided withia well casing' provided with bracketsat-top and bottom, a bearing p ost extendin .centrally in' thersaid well casing and fixe atjits ends in the said brackets, a

series of pumping elements having hubs1 )mounted to turn on the said bearing post, a

tubulardriving shaft made in sections secured to the said hubs, the said bearing post extending loosely through the said driving shaft sections, and driving means at the upper'end, of the driving shaft for drivingthe .latter and' with it the pump elements.

' 4f. A rotary pump'of the class described provided with a wen casing provided with brackets at top and bottom, a bearing post extending centrally in the 'saidwell casing and fixed at its ends in the said brackets, a series of pumping elements having hubs mounted to turn ontlie said bearing post.a tubular drivingshaft made in .sections secured to the said hubs, the said bearingf post extending loosely-through thesaid driving shaft sections, a' 'bearing -on the bottom bracket for the lower .end of the hub. of the lowermost pumping element adapted to close the latter ,in fluid tight relation, and a bearing 'at the top bracket for the uppermost driving shaft sectionl to turn in, Vand driving .means `on the upper end of the driving shaft.

A rotary pump of the class described,

o n the lower end of the said well casing and projecting below the same, the said bracket having water inlet openings and a central portion, a bracket at the upper end of the lcom risin a well casin a bracket secured said well casing, a bearingj'post fixed in the said top and bottom brackets and extending centrally through the casing, ya series of pumping elements having hubs journaled on the said post, asectional driving shaft secured to. the hubs of the pumping elements and through which extends loosely the said fixed bea-ring post, said central portion of ...said lower bracket formingfa bearing step -rto engage the hub of the'lowermost pumping element in fluid tight .relation and thus close the lower end of the shaft, and upper bearings on the said bracket for the'upper end of tlie 'said driving shaft.

In testimony whereof I have signed my name to this. specification in the presence of two subscribing witnesses.
